Pumpkin Spider Add-on 1.20+

A simple way to prepare for Halloween is to add the Pumpkin Spider mod to Minecraft. It introduces a new kind of monster that has a unique and quite terrifying appearance with a smiling face on its back. This mob is not a boss but will be a regular enemy in your survival game. If you're looking for some variety in the blocky universe or are already prepping your world for the upcoming holiday, this is one option to consider.
